Why is it important to use high quality FEP film?

It’s no secret that the FEP film in the bath is an important element, both for print quality and for maintaining the printer’s performance.

  1. Fluorinated ethylene propylene film with good release properties, resistant to high temperatures (220°C) and UV radiation.
  2. The right film improves the quality of the product, reduces waste and lasts longer than the wrong one.
  3. High-quality film allows you to increase the speed of printing without losing the quality of the product.
  4. The thinner the film, the more accurately the model is printed, since the image is sharper. This is important for LCD. With DLP, the focus point can be changed.
  5. High-quality film – uniform thickness over the entire surface.

How to replace Fluorinated ethylene propylene (FEP) film?

If you see cloudiness on the film, white streaks, spots, so it’s time to change the Fep film.

Where to start?

  1. Carefully remove the bath from the printer
  2. Drain off the remaining polymer
  3. Next, figure out what size of film you need. There are A5 and A4
  4. Next, turn the bath over and carefully unscrew the screws.

The film has been removed. Let’s move on to the replacement:

  1. Carefully look at which side we put the film up to the polymer. For example, on our films in the corner a dot is drawn with a marker, if it is erased with a fingernail, then this side is up under the polymer.
  2. It is recommended to put a bottle cap or something similar on a clean surface. Then we put the mount from the bath and the film on top. Why did we put a stopper? To leave a small gap on the film for framing the tub under the last screws.
  3. In order not to break through the film with screws (this may cause microcracks), you need to take a soldering iron with a thin tip and solder the holes for the screws. If there is no soldering iron, you can take a nail or an awl and use a lighter.
  4. Assemble the frame and the bath together, tighten all the screws tightly.
  5. As a last step, to cut off the remaining film around the entire perimeter of the bath with a sharp knife.
